This yinvention relates to magnetic scpa. vrators.

- There are a number of small mining inilrateiyiand 'that differ considerably in their i.' magnetic ,properties and ,also .inthe rate at which 'they can be 'supplied-from the mine.

.--Iiijalv separate magnetic separator were pro-I vided for each i ade of ore, none of the .s'eparatorsvvould e `fully utilized as regards I' flits' magnetic' structiuebecause of the variable l-rate 'of supply ofthe ores.

` The "chief object of the present invention.

l is to enable various kinds of ore to be treated simultaneously but separately `from each other, in a magnetic separator common to all the o res. l

VThe invention `isparticularly applicable to separators ofrthe kind in which a horizontal rotatable 'cylinder composed of disks serves as armature to an underlying magnet pole, ,between which and the cylinder the material to be treated is made to travel transversely with respect tothe axis ofthe cylinder.v l v According to the present invention the magnetic separator isso constructed that the complete magnetic field across which the material to be treated is conducted is subdivided into artial fields .the strengths of which dilier liom one another.

In order to adapt the strengths of the several partial lields as far as possible to the different magnetic properties of the different kinds of ore, the Widths of the gaps of the artial elds are .adjustable independent y of each other. By making the width of each individual field variable provision is made for the variable rate of supplyof the' ores and for complete utilization of the magnetic structure.

The invention an be carried into practice in various' ways and is applicable to separators of all kinds in which the path taken by the material during its introduction-into the Specification o Lettersllatent. '-7 fattQd-.tf

The lamell can be combined into groups of different Width that is the groups may diiier as regards the number of the disks composing them. In the drawings three such groups are illustrated The material tobe treated is lsupplied to each group of lamelles at n of the feeding de- .vice h, Fig. 2. In'the several partial fields of the complete magnetic lield, the magnetic material is attracted onto the sharp edges of the rotating disks d which carry it out side the field, and finally, in as far as it does "-LQt-zfall (lf itself,'it is mechanically reinoved,
